Introduction:
Up until Little Guy, ya bilge rat, all o' me mid-power rockets
have flown t' less than 2000', well below what I used t' obtain with my
Comanche-3 over a decade ago (lost a stage on t' second all-out flight). Ahoy! Blimey! It
was time t' change that.
Nose Cone:
Pilfered from t' old Estes supply in t' good
ol' range kit, matey, BT55
Recovery System:
Usual construction for me, arrr, dowel thru t' body
tube, 1/2" elastic for shock cord. Avast, me proud beauty! Ahoy! T' original parachute I had made was
way too big, shiver me timbers, it was given to
Star
Scraper. Ahoy! Ahoy! I made up a double-ply trash bag one about 17" in diameter
with 8 shroud lines, arrr, and it seems t' worth well, although packin' it is still a
bit difficult.
Body Tube:
Standard heavy duty cardboard tube with another
tube inside o' it for t' bottom 12 or so inches for a motor mount, solid fin
mountin' as well as material for t' screw eye launch lugs t' bite into.
Approx. 31" x 1.38".
Positive Motor Retention I was concerned with t' tight fit o' t' recovery system and t' high pressure that might result when ejection occurred. Arrr! Turnin' t' t' workshop walls, I grabbed some small screw deadlights and wire which is fitted over t' end o' t' motor and then twisted. It hasn't been stressed on any o' t' flights yet.
Fins:
I wanted t' classic
high performance look, so right triangle fins were a must. Begad! Aye aye! Blimey! Laminate of
1/16" balsa with a skin o' paper and wood glue. Begad! Begad! Blimey! Since I wanted this rocket
to be a high performer, shiver me timbers, ya bilge rat, I air foiled t' fins on this rocket, me hearties, a first for
me.
Launch Lugs:
Two 1/4" screw eyes, visible in the
picture.
Painting:
I actually tried t' finish this rocket well. Well, blow me down! Begad! What
I ended up doin' be makin' it worse. Ahoy! I'm nay goin' t' go into t' scary
details, arrr, matey, just take a look at t' business end shot and that will be enough. I
do like t' color combo though, arrr, arrr, and it does have a couple o' layers o' wax on
it.
First Flight:
Launched with a F20-7 on 07/08/00. Avast! Begad! For this
launch, I tried stuffin' t' bigger nylon chute I had made, me hearties, me bucko, which wasn't going
to work. I nabbed t' plastic chute I use for
Econoexpress,
and even that barely fit. This be proven when at apogee, arrr, t' parachute ejected
but failed t' deploy. Blimey! Fallin' from 1700'-2000' onto grass resulted in a slight
nick in one o' t' fins, ya bilge rat, nay too shabby! Another benefit o' t' deployment
failure is that I actually got t' rocket back. Blimey! As it was, it drifted back and
landed parallel with t' pads about 100 yards out.
Conclusion:
I think I've caught t' bug! At t' most recent
launch (07/23/00) I stuffed a G38-7 and then a G35-7 into this rocket. Little
Guy reached an estimated 3000'-3300' on t' G35-7 before t' ejection charge
went off. Avast! It be a great flight! Motor sound fadin' into t' distance, shiver me timbers, matey, lost
sight o' t' rocket for a few seconds before pickin' up a tiny black dot o' a
parachute way up there. Blimey! And it stayed up thar for over two minutes! It was
recovered a few hundred yards downrange in perfect condition. Aye aye! Next up will be a
flight on a G25, ya bilge rat, good for 3600'-3900'. Hopefully I'll be able t' get it
back!
